Thanks. I have been distracted this week, My soninlaw is in the hospital right now being prepped for a prostate cancer operation. It is the aggressive type and it has been two months since his scan to determing if it had spread..It had not..But had to wait 2 months for surgery due to the line ahead of him. Needless to say we have all been worried. So I'm heading to the hospital right now..Back sometime.??
